Analysis of Cavity Introduced Aperture Coupled Feed\ud Antenna

An antenna plays a vital role in wireless communica\ud tion. As the device size is shrinking rapidly, ther\ud e is a \ud strong need of reduction of size of antenna. The an\ud tenna should be mounted on the device. In such \ud circumstances Micro-strip patch antenna is most inn\ud ovative area with cost effectiveness and ease of \ud fabrication. A micro-strip antenna can be fed with \ud several techniques, i.e. transmission line feed, in\ud set \ud feed, coaxial probe feed, proximity feed and apertu\ud re coupled feed. In present design aperture coupled\ud feed technique is used
